Co to jest?

Bluetooth LE Audio represents a complete rethinking of wireless audio transmission. While arilier Bluetooth audio standards were built on a foundation called Classic Audio, which ch relied on SBC codec anda point-to-point connection model, LE Audio proveles a new architecture optimized for low power consumption, high efficiency, and explible audio routing. The concorporaste of this architecture tture is the Low Complexity Communiciations Codec (LC3).

LC3 is thee mandatory codec for Bluetooth LE Audio, and it delivers a dramatic improwitement over thee SBC codec used in Classic Audio. At any given bitrate, LC3 provides consignatly better audio quality.
